Scintilla provides numerous lexers, most of which Notepad++ is not using. They are just sitting there...so why not take advantage of them! Below is a list of the SCLEX_xxx defines that are not used within the ScintillaEditView::langNames array. I don't know what most of them are or if they all are applicable but I'm sure many of them could be used. I'd like conformation from @donho that pull requests adding many of these lexers would be accepted.
